FAQ | VuAppStore

Short answers to the questions we are asked most often. The longer, categorized FAQ lives at /support/faq; the architectural details live at /privacy.

How is this priced?

$0.01 per bit. A single VU app is $2.56 (256 bits of symmetric encryption × $0.01). Any 10 apps in one purchase is $25.60. The full VU Suite, including future apps, is $256. There are no subscriptions and no auto-renewals. The full mechanism is documented at /512-license and /how-licensing-works.

If you cannot see my data, how do I sync between devices?

Each VU application picks the synchronization model appropriate to its threat model. Most apps default to per-device storage and an encrypted-export workflow. A few apps that need real-time multi-device behavior use end-to-end-encrypted relays where the server only sees ciphertext. Per-app behavior is documented in each app's privacy disclosure inside the /apps catalogue.

What if I forget my password?

Your encrypted data is gone. We mean this literally. See /no-recovery for the long version and the architectural reason.

How do I know you are not lying about all this?

Three answers, in order of strength:

The storefront and the licensing endpoints are published at github.com/vuappstore. You can read them.
The cryptographic primitives we rely on (WebCrypto, @noble/curves, @noble/hashes, RSA blind signatures) are public and well-known. Anyone with crypto background can verify how we use them.
The warrant canary at /warrant-canary is updated quarterly, and the transparency log at /transparency records every government request we have received.

You should not take our word for it. The whole point is that you do not have to.

What happens if VuLabs Inc goes out of business?

The static site continues to work from any mirror, including any local copy. Because each VU app runs entirely in your browser and stores its data locally, our absence does not affect your data. Only the licensing endpoints would stop accepting new purchases.

Why not native iOS or Android apps?

App stores require:

Apple Developer or Google Play accounts that we would have to identify ourselves to.
Submission of binaries the platforms can hold or reject — a kill switch we do not want.
Mandatory advertising IDs in many cases.

Progressive Web Apps avoid all of this. You install them from this site, they run as real apps, and the platform never decides whether you are allowed to have them.

How do you make money if there is no advertising and no analytics?

License sales. $2.56 per app, $25.60 per ten-pack, $256 per suite, paid in cryptocurrency. Our edge functions verify the payment; the blind-signature scheme prevents us from learning who you are.

Are you GDPR or CCPA compliant?

We process essentially no personal data, so the substantive obligations of these laws are trivially satisfied. The relevant disclosures, including the formal data-protection contacts, are at /legal/gdpr and /legal/ccpa.
